What is the difference between a thermal/magnetic and a mag only breaker?
What is the different between a thermal/mag breaker and a mag only motor circuit protector?
Product Line:
Molded Case Circuit Breakers
Resolution:
The thermal/mag has both thermal (for overload trip) and magnetic (for inrush/instantaneous trip) elements. This is used primarily for conductor protection. The mag only does not have thermal protection and is mainly used for motor protection.Released for:Schneider Electric USA

SUMMARY
Thermal magnetic breakers are affected by ambient temperature
and are best used in applications where temperatures do not fluctuate
far from the reference ambient temperatures for circuit breakers,
25°C (77°F) and 40°C (104°F).
.
SUMMARY
Hydraulic magnetic circuit breakers are best used in harsh
environments where temperatures can vary widely.
