LMLPK11-2R-33751-1-V Circuit Protection

Introduction

LMLPK11-2R-33751-1-V is a circuit breaker designed for use in residential and commercial applications. This combination circuit breaker features two pole breakers with 40 amp/3-120 volt and 60 amp/1-277 volt elements. It also has a common trip lever with handle type B (slow-make/slow-break) rated for 40 amperes. It is suitable for use in single phase three or four wire electrical circuits.

Application Field

The LMLPK11-2R-33751-1-V circuit breaker is suitable for use as the main switch in residential and commercial buildings, as well as for any applications that require two pole breakers with voltage ratings of 3-120V and 1-277V. It is also suitable for single phase three or four wire electrical circuits. This circuit breaker is ideal for circuit protection and overload protection in panel boards, switchboards, and similar equipment.

Working Principle

The LMLPK11-2R-33751-1-V circuit breaker works by automatically cutting off the flow of electricity when too much current flows through the protected circuit. It does this by sensing the current that is flowing through the circuit and comparing it to the maximum rated current of the breaker. When the current exceeds the rated maximum value, a circuit breaker trips, disconnecting the circuit. This reduces the risk of fire, electric shock, and other hazards.

Advantages

The LMLPK11-2R-33751-1-V circuit breaker has many advantages compared to other circuit breakers. Firstly, it provides a reliable way of protecting circuits from overloads and short circuits. It also offers a high current capacity, quick response time, and radio frequency interference protection. In addition, the trip lever handle type B offers improved safety as it is slow-make/slow-break rated for 40 amperes.

Disadvantages

The main disadvantage of the LMLPK11-2R-33751-1-V circuit breaker is that it is not suitable for use in hazardous areas. Additionally, it may not be suitable for applications that require more than two pole breakers and/or higher voltage ratings. Further, it is not UL listed, so it may not be accepted in all areas.

Conclusion

The LMLPK11-2R-33751-1-V circuit breaker is a reliable and effective way of protecting circuits from overloads and short circuits. It features two pole breakers with 40 amp/3-120 volt and 60 amp/1-277 volt elements and a common trip lever with handle type B. It is suitable for single phase three or four wire electrical circuits in residential and commercial buildings. It is, however, not suitable for hazardous area applications.
