Schneider Electric TeSys GB2 Thermal Circuit Breaker -, 3A Current Rating 1-Pole, DIN Rail

This thermal circuit breaker is designed to provide overcurrent protection for control and distribution applications in industrial and commercial systems. It operates on thermal‑magnetic trip principles and is intended for DIN‑rail mounting, offering Compact protection suited to AC and DC networks within moderate power circuits.

• 3A rated current delivers precise low‑current protection for control circuits
• 3kA breaking capacity limits fault energy at typical supply voltages
• Thermal‑magnetic trip offers both overload and short‑circuit response
• Toggle reset actuator enables Rapid manual reclosure after fault clearing
• Cable Terminal connections accept standard solid and flexible conductors
• 4kV impulse withstand reduces susceptibility to transient overvoltages

• Suitable for protection of control panels and automation modules
• Ideal for branch circuits in building services and machine control
• used with 48V DC control supplies and signalling circuits
• Can be used for AC motor control auxiliaries and pilot circuits

It clips directly onto standard DIN rails or can be mounted on a plate using the provided clip system for flexible installation.

Terminals accept solid conductors from 0.75 to 6mm² and flexible conductors with ferrules up to 4mm² depending on the connection point.

The device meets shock and vibration criteria withstanding 22Gn shocks for 20ms and vibration up to 5Gn across 5 to 110Hz.

It has IP20 protection, operates from −20 to 60°C, stores at −40 to 80°C, and uses halogen‑free plastic parts for reduced fire risk.
