4 Motor Circuit Protectors - MN Series
Motor Protective Circuit Breakers MN Series - Overview
EEC's new generation of Manual Motor Protectors provide a very compact solution for operation and protection in motor control applications. The NEC requires four functions to be considered a combination motor starter: Motor Disconnect, Branch Circuit Protection, Motor Controller and Motor Overload Protection. EEC's MN series meets all of these requirements, and the UL/CSA requirements for Self-Protected Motor Controllers to be used in Type-E & F applications. With worldwide approvals the EEC's MN serie s can be used in a variety of applications all over the world.
Combination starters are the most common type of packaged motor controllers. They are called combination because of their construction and combined functions required by the US National Electric Code (NEC) and Canadian Electrical Code (CSA) Motor Disconnect, Motor Branch Circuit Protection, Motor Controller and Motor Overload Protection. UL & CSA (hamonized) currently recognizes six different types of combination starters that meet the requirements of a motor branch circuit.
Constructions Types A through D are traditionalstarters that use either a listed disconnect switch andfuses or a listed circuit breakers as the disconnectmeans and for short circuit protection. Each type usesa separate UL 508 & CSA 22.2 #14 listed motor controller and overload relay. Recently revisions on UL508 & CSA 22.2 #14 introduced the Type "E" and Type "F" starters.
Type "E" starter is a self-protected combination motor controller that combines in a single device all the required functions of a combination starter and eliminates any additional requirements for upstream fuses or circuit breakers. These starters clear faults within their rating without sustaining damage to themselves or the rest of the system, being able to get back into operation. There are two arrangements for aType E starter: manual (as stand-alone) and associatedwith a contactor. Both are submitted to the same testssequences.
Type "F" starter consists of a listed manual Type "E" combined with a UL508 & CSA 22.2 #14 listed contactor. The differencebetween the two types is related to the absence of self-protected characteristic; hence, Type "F" has softened tests sequences allowing damages on the contactor after a fault.
Tests performed in order to fulfill the Type "E" requirements are considered the hardest in UL & CSA, including short-circuit and endurance tests on the same sample. As a comparison, UL Type "E" exceeds the requirements for Type "F" and IEC60947-4-1 Coordination type 2.
EEC's self-protected combination Type "E" combinesall of these functions within a single product for a manual operation or within a set of two products (with a listed contactor) for a remote operation. They are preferred for a wide range of applications where traditional full voltage combination starters have been required. Some examples are: Pumps, Industrial Washing Machines, Compressors, Blowers, Cutting Machines, Conveyors, Lumber Processing and many others.
The Manual Type "E" Starter is a stand-alone product that ranges from fractional up to 60Hp @ 575V motors (0.16 to 65A) with up to 65KA @ 480V and 25KA @ 600V interrupting shortcircuit capability (MN65). Together with a complete line of accessories, the MN series are a compact and reliable solution for starting and protecting motors.
In addition to its popular line of UL/CSA enclosed starters,EEC is now introducing a new line of combination starters, with optional ratings from NEMA 1, 4, 4X, 12 & 13. EEC's enclosed Type "E" & "F" Starter featuring as standard a handle for disconnect means - MN Series are "Suitable as a Motor Disconnect" - through the door and a contactor for remote operation. Provisions for control circuit transformer, operators, pilot lights and a variety of accessories are available to meet each applications requirements.

5Motor Circuit Protectors - MN Series
Introducing our latest in technology and design, EEC's MN Series Motor Circuit Protectors save panel space and can be used in most applications in motor control.It combines short-circuit and motor overload protections in just one component. These devices include a three-position rotary ON-TRIP-OFF handle, which can be padlocked in the OFF position.

Type “E” Coordination - LSN Series
Manual Self-Protected Combination Motor Controller - Type "E"
• No need of upstream protective devices such as UL489 MCCB or UL248 fuses• Built-in protections: disconnect means, short-circuit protection, motor control and overload protection• Short-circuit interrupting capacity up to 100kA@480Vac (50kA@600Vac)• Compact combination starter• Phase loss sensitivity• Ambient temperature compensation -4…+140ºF (-20…+60ºC)
Ordering example: the type can be found in the “Rated operational power” column alongside the selected rating 5.0hp @ 575V with a 120VAC desired type: MN32CH063-N4A = MN32H063 + MNADLS1 + LSN4-310-A (120VAC Coil - 50/60Hz).

Motor Protective Circuit Breakers - Characteristics Curves
The tripping characteristic shows the motor circuit breaker trip time in relation to the rated current.The curves show average tolerance range values for an ambient temperature of 20 °C, starting in cold state. Thermal trip time when working in operating temperature is reduced to around 25% of the presented values. Under normal operating conditions, all 3 circuit breaker phases must be conducting.
