Thermal Trip Unit for MCB Miniature Circuit Breaker (3051692)
1. The contact is the conductive part of the circuit breaker that directly contacts or separates to open and close the circuit. It is divided into static contact (fixed) and moving contact (movable) according to the state of movement. Its core function is to conduct current and break arc. 2. The operating mechanism is a mechanical system that drives the contact to open and close. Its core functions are: ① Provide sufficient power to make the contact close or open quickly; ② Keep the contact pressure stable in the closed state; ③ Quickly trigger the disconnection in the event of a fault (cooperate with the release).
In HAIPART's environmental simulation laboratory, each thermal trip unit undergoes 720 hours of extreme testing at temperatures ranging from -40°C to 250°C. The specially developed ceramic base material ensures ±1.5% operating accuracy even in harsh environments such as oil, dust, and other contaminants. The data curves printed on the test report ultimately translate into uninterrupted production in the customer's workshop.
Why choose the HAIPART Thermal Trip Unit?
✅
Dynamic matching technology
✅
Full lifecycle management
✅
From passive protection to active prediction
Applications:
Suitable for data centers, marine power generation, electric vehicles, and other applications.
