The contactor carries an overvoltage category III rating and pollution degree 3, making it suitable for fixed industrial installations where transient overvoltages are expected. The TH protective treatment per IEC 60068-2-30 confirms it withstands tropical humid environments.
Mounts on DIN rail or plate. The 45 mm wide, 74 mm high, 80 mm deep footprint fits standard panel layouts. Screw clamp terminals accept 1 to 4 mm² flexible or solid conductors on both power and control circuits. Tightening torque is 1.2 N.m for all terminals — consistent, so one torque driver setting covers the whole install.
Performance and durability
Rated for 10 million mechanical cycles and 300,000 electrical cycles under AC-1 load. The 25 A AC-1 rating at ≤55 °C is the headline figure for resistive switching; the associated fuse recommendation is 25 A gG at ≤690 V for type 1 coordination. Breaking capacity is 96 A at 440 V, making capacity 120 A at 440 V AC — both per IEC 60947. The 2.5 mOhm average impedance per pole keeps heat dissipation at 2.6 W per pole under AC-1 load.
