Product details

Breaking capacity sits at 4.5 kA per EN 60898 and 6 kA per IEC 60947-2, with a 5 kA rating under UL 1077 / CSA C22.2 No.235 for North American acceptance.

Combined terminals (top and bottom) simplify daisy-chaining.

Rated for ambient temperatures from -25 °C to +55 °C, with derating above 40 °C per the thermal curve. Mounting position is any, which gives flexibility in crowded enclosures. The quick-assembly system clips onto standard DIN rail;

Rated according to EN 60898 (4.5 kA), IEC 60947-2 (6 kA AC, 15 kA DC), and UL 1077 / CSA C22.2 No.235 (5 kA). The DC rating at 72 V max (15 kA per IEC 60947-2) covers control-circuit protection. Energy limiting class 3 — fast enough to limit let-through energy for downstream component protection.

Frequently asked questions
