The DAM1 series circuit breakers are designed for reliable current interruption in electrical systems. These thermal-magnetic breakers combine precise overload protection with instantaneous short-circuit response, making them ideal for industrial applications.

DAM1 circuit breaker front view

Thermal protection is achieved through a bimetallic strip that bends proportionally to current magnitude, triggering disconnection during overload conditions. The magnetic trip mechanism responds instantly to short-circuit currents, protecting connected equipment from damage.

DAM1 breaker internal mechanism

Available in fixed type configurations, these breakers support operational voltages up to 400V/415V with rated currents ranging from 63A to 250A. The arc chamber design ensures safe interruption of high fault currents while maintaining system integrity.

Key applications include power distribution panels, motor protection circuits, and industrial control systems where reliable circuit protection is essential. The breakers' compact design allows for space-efficient installation in electrical enclosures.

DAM1 breaker side view

All DAM1 series breakers undergo rigorous testing to ensure compliance with international standards including EN 60947-2. The molded case construction provides durability in demanding industrial environments while maintaining electrical isolation properties.
