Schneider Electric TeSys TeSyS GB2 Thermal Circuit Breaker - 1-Pole, DIN Rail, 2A Current Rating, 10 kA, 250V, 48 V dc

This thermal circuit breaker is a single-pole protective device designed for control and automation panels where compact, resettable overcurrent protection is required. It combines a thermal trip element with a magnetic short‑circuit response to protect circuits in AC and DC networks while mounting neatly on DIN-rail systems.

• 10kA breaking capacity supports high-fault current interruption
• 2A rated current delivers defined protection for low-current circuits
• Thermal-magnetic trip offers both overload and short‑circuit protection
• Toggle reset actuator enables quick manual reclosure after trip
• Cable terminals accept 0.75 to 6mm² conductors for flexible wiring
• 4kV impulse withstand improves immunity to transient overvoltages

• Suitable for control panels in industrial automation systems
• Ideal for protection of DC control circuits at 48V
• Used with motor starters and contactor control coils
• Can be used for distribution branches in machine electrical cabinets
• Suitable for retrofit installations on 35mm DIN rails

It is designed for both AC and DC operation, with rated operational voltages of up to 250V AC at 50/60Hz and 48V DC.

It clips onto standard 35mm DIN rail and is compatible with both horisontal and vertical mounting positions.

The device accepts solid conductors up to 6mm² and flexible conductors with or without ferrules within the specified ranges, secured with 1.2N·m tightening torque.

It is specified for 8,000 mechanical cycles and 8,000 electrical operations to ensure long service life under normal operating conditions.
