It carries 3 instantaneous contacts rated at 10 A at 24 V, with a 24 V DC coil drawing 1.6 W closing power. The built-in diode surge suppressor handles coil suppression — no external free-wheel diode needed.
The mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° tilt forward/backward. Clearance requirements are tight — 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side. Panel builders can plan for a 45 mm wide × 57.5 mm tall × 73 mm deep envelope.
24 V DC coil, 10 A rated switching at 24 V, 3 instantaneous contacts, Size S00, with a diode surge suppressor. Operating temperature range -25 to +50 °C; storage -55 to +80 °C.
