Product details

Product Overview and Key Ratings

The C16B3TM080C: Breaking capacity is rated at 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, with higher ratings at lower voltages: 40 kA at 220/240 V AC, 20 kA at 440 V AC, and 15 kA at 500 V AC. The TM-D trip unit provides L (thermal) protection for overloads and I (magnetic) protection for short circuits, with the 80 A rating at 50 °C.

Mechanical and Electrical Durability

Electrical durability is rated at 40,000 cycles at 440 V at half rated current (In/2), 20,000 cycles at 440 V at full rated current, and 15,000 cycles at 690 V at In/2. Mechanical durability is 40,000 cycles. These figures support the breaker's use in applications with moderate switching frequency, such as panel feeder protection.

Mounting and Environmental Specifications

The 105 mm width, 161 mm height, and 86 mm depth fit standard ComPacT NSX cutouts.
