Name: L2 Manual Reset Thermal Switch Circuit Breaker
Brand: Senreach
SKU: 197364790

Products Description

L2 Series Single Pole circuit breaker represents our largest selling product family. Based on a proven "SNAP ACTING" bimetallic thermal sensing element system, L2 Series circuit breakers sense overload conditions and interrupt the flow of current. The resettable actuator mechanism then remains disengaged until manually reset.

L2 Series offers amperage ratings from 3A to 25A, and is suitable for a diversity of applications. Our products are carefully calibrated and tested to ensure reliable performance under a variety of operating assignments and conditions.

L2 Manual Reset Thermal Switch Circuit Breaker is easy to install, durable in use, and suitable for automotive, inudstrial, marine etc. It is widely used in household and commercial appliances, transportation, marine, telecommunications, power strips, audio-visual, medical, and power supplies.

Working principle

The circuit breaker is an electromechanical device whose function is to protect electrical installations, being used in electrical distribution boards. It works by interrupting the electric current when it exceeds its design limitations, therefore preventing the supply of energy to the loads, and damage to the circuit.

When the system is over power or short circuit, the breaker will cut and save your equipment. No need to replace the fuses, the system can be reset by a simple switch which also offers safe and instant system shut down.

Product advantage

can be reset after a disconnect over a period of time, then you can press the reset switch to use it again.
Compact design enables high density circuit protection configuration. Made of durable plastic, thermal overload protector is high quality and long service life.
Thermal Circuit Breaker is widely used in automotive, industry and ocean industry.
