Four normally-open instantaneous contacts, labeled 53/54, 63/64, 73/74, 83/84. All four are independent current paths. The headline rating is 10 A maximum — that's the thermal current (Ith) carrying capacity. What matters for your specific control voltage is the switching capacity at that voltage: 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V. For AC-15 inductive loads (solenoids, contactor coils) at 690 V, the rated value drops to 1 A — the 690 V insulation voltage with pollution degree 3 supports this, but the switching current is limited by arc extinction capability at that voltage. Mechanical service life is 10 million switching cycles typical.
Spring-loaded terminals for auxiliary and control circuits. Accepts 2x (0.5 to 1.5 mm²) with ferrule, or 2x (0.5 to 2.5 mm²) without ferrule. AWG equivalent is 2x (20 to 14). No screw torque to verify, no loose connections from vibration — spring-cage holds until you press the release. The 47.7 mm depth includes the terminal projection; the 36 mm width and 41.5 mm height match the contactor relay footprint.

Environmental and protection class
IP20 on the front — protected against solid objects over 12.5 mm, no water protection. That's standard for inside a control cabinet.
