The BW & BH series thermostats provide reliable protection against over-current and over-temperature conditions. These sealed units feature small internal resistance, operate silently, and reset automatically. The bimetallic components respond to both temperature and current changes, altering their state to either cut off or complete the circuit as needed for protection.

The BH series offers enhanced safety compared to standard protectors, with immediate response to sudden current surges without temperature lag.

H20/H21 Series Principle and Structure

These universal protectors feature large metal casings containing bimetallic components with silver alloy contacts, conductive brackets, and insulation stands. During abnormal operation, rising temperatures cause the bimetallic components to quickly open the circuit, automatically resetting when temperatures return to safe levels.
