The E-T-A 1610-H2-20A is a miniaturized, single-pole, press-to-reset, cycling trip-free thermal circuit breaker. It is specifically designed for automotive fuse block installation, extending the benefits of circuit breaker performance to cost-critical applications.
This thermal circuit breaker has a current rating of 20A and a maximum voltage rating of 32VDC. It operates within an ambient temperature range of -40°C to +85°C. The breaker features a push-to-reset actuator and is designed for mounting in a holder.
Typical applications include extra-low voltage wiring systems on all types of vehicles and marine craft. The breaker meets UL1500 approval standards. It offers a service short-circuit breaking capacity of 300 operations at ≤ 50A and an ultimate short-circuit breaking capacity of ≥ 3 break operations at 150A, or ≥ 1 break operation at 2,000A.
Environmental testing includes vibration resistance up to 10g, shock resistance of 50g, 96-hour corrosion resistance, and 240-hour humidity resistance. The degree of protection for the operating area is IP30.
The maximum operating voltage is 32 V DC.
The nominal current rating is 20 A.
It uses a push to reset actuator.
The operating temperature range is -40 to 85 °C.
The degree of protection is IP30 for the operating area.
Service short-circuit breaking capacity is 300 operations at ≤ 50 A. Ultimate short-circuit breaking capacity is ≥ 3 break operations at 150 A or ≥ 1 break operation at 2,000 A.
