SCHURTER TA35 thermal circuit breaker for equipment, 1-pole, rocker, 0.05–20 A, 240 V AC

SCHURTER TA35 is a thermal circuit breaker for equipment protection: overcurrent protection and on/off switching in one housing for a panel cut-out. Single-pole rocker version with snap-in mounting, currents 0.05–20 A, 240 V AC / 32 V DC. TA35 replaces the combination of a switch and a fuse in instruments, industrial power strips, power supplies and racks.

The rocker both switches the circuit and shows its state. Positively trip-free: on overload the thermal element opens the contact even if the rocker is held. Short-circuit capacity 2 kA, mechanical life 50,000 cycles. It is a supplementary protector for equipment to UL 1077 / IEC 60934, not a miniature circuit breaker for distribution boards to IEC 60898.

Key features:

• Thermal release, 1-pole (2- and 3-pole versions in the series)
• 0.05–20 A, 240 V AC, 32 V DC
• Positively trip-free: holding the rocker does not prevent tripping
• Life 50,000 mechanical cycles, 30,000 at 1×In AC
• Snap-in, IP40 front, temperature −30…+60 °C
• UL 1077, CSA C22.2 No. 235, IEC 60934, GB 17701
