FAQ
What is a shunt trip on a circuit breaker?
A shunt trip is an accessory for circuit breakers that enables remote tripping via an external electrical signal (e.g., fire alarm, emergency stop systems), enhancing safety by cutting off power when triggered.
Where are shunt trip breakers required?
Commonly used in commercial/industrial settings like data centers, elevators, and fire protection systems, where remote power cutoff is mandated for safety compliance.
How to reset a shunt trip breaker?
First, resolve the external trigger (e.g., clear alarm), then manually reset the breaker to the "ON" position after ensuring no fault persists.
Are shunt trip breakers normally open or closed?
Normally closed (conducting current) under standard conditions; they trip open only when an external signal activates the shunt coil.
What types of shunt trip circuit breakers are available?
Available by current rating (10A–630A), poles (1P–4P), and mounting (DIN rail/panel), compatible with MCCBs and miniature breakers.
What certifications do your shunt trip breakers have?
Compliant with global standards (IEC, UL, CE) and major safety certifications for international markets.
Do you support OEM for shunt trip circuit breakers?
Yes, OEM services include custom parameters, branding, and packaging tailored to client requirements.
What is the lead time for shunt trip breaker orders?
Lead times vary by region, typically 2–4 weeks. Contact sales for exact delivery timelines.
How to contact distributors for shunt trip breakers?
