ETA Thermal Magnetic Circuit Breaker 1A, 1-Pole, Panel Mount, Screw Terminal, 240V AC, 3400-P10-H-SI-1A

ETA 3400-P10-H-SI-1A Thermal Magnetic Circuit Breaker is engineered for precision overcurrent protection in panel-mounted electrical systems. This single-pole breaker offers a 1A current rating and combines both thermal and magnetic tripping mechanisms, providing effective protection against overload and short circuit events.

Designed for industrial and automation applications, the circuit breaker features manual reset functionality with a tease-free, trip-free actuator button. The device’s delayed overload characteristic allows safe shutdown, with a typical tripping time of 20 - 30 seconds at twice the rated current, minimizing nuisance trips while safeguarding wiring and equipment.

Rated for operation at 240V AC and 80V DC, the breaker is suitable for a broad range of electrical environments. Its medium break time and 25A breaking capacity make it ideal for use in control panels, machinery, and modular distribution boards. The panel mount design with a compact form factor (14.5mm width x 50.8mm height) and screw terminals ensures quick and secure installation, supporting single-hole mounting for convenience.

Single-pole operation enhances separation and control in branch circuits. Thermal-magnetic convertible mechanism ensures reliable response to overloads and short circuits. Manual pull and reset actuator supports safe operation and maintenance.

Auxiliary contacts for signaling facilitate remote monitoring and integration into automation systems. Insulation resistance exceeding 100MΩ maintains electrical integrity and operator safety. Compliance with CE and RoHS standards ensures quality and compatibility in regulated environments.

With a typical service life of 5000 operations, the ETA 3400 series breaker offers robust performance for demanding applications in industrial, laboratory, and commercial settings. Use cases include power distribution panels, process machinery, HVAC control, laboratory electronics, and other critical systems requiring dependable overcurrent protection.
