Product Details
Altech R-Series DIN Rail
Thermal Magnetic Circuit Breakers are found in most distribution boards. The thermal portion provides an "inverse time" response feature, which trips the circuit breaker sooner for larger overcurrent’s. The Altech R-series are primarily DIN Rail mounted and provide a compact solution to your protection requirements. All models are highly reliable and excellent quality.
