104-PR-1A Description

Short technical summary and product information.

The E-T-A 104-PR-1A is a single pole thermal circuit breaker in a miniaturized design. It utilizes a positively trip-free snap action mechanism for reliable switching. Rated at 1A with a voltage rating of 240VAC and 48VDC, it provides overcurrent protection for a variety of applications.

 

The breaker offers a dielectric strength of 3000VAC and insulation resistance greater than 100 MΩ at 500VDC. It has an interrupting capacity of 6A (6 x IN) and a rupture capacity of 2000A at 250VAC and 200A at 48VDC per UL 1077. The operating temperature range is -20°C to 60°C.

 

This component is designed for through hole mounting with solder pin terminals and features a push-to-reset actuator. It carries approvals from VDE, UL, CSA, and CQC, ensuring suitability for global applications. Environmental resistance includes vibration (10 g), shock (25 g), corrosion (96 h salt mist), and humidity (240 h at 95% RH) with an IP40 (operating area) / IP00 (terminal area) degree of protection.
