Product details

The coil is rated for 83 to 155 V AC/DC, with a pickup threshold of 0.8x rated value and a dropout around 0.55x. Inrush peaks at 1.5 A; steady-state draw is 2 VA at 50 or 60 Hz.

Switching performance and contact ratings

Switching frequency varies by duty: up to 1,200 ops/hr in AC-1, 1,000 in AC-3, 750 in AC-2, and 300 in AC-4. Arcing time is 10–20 ms; operate time is 30–55 ms for both AC and DC coils. Auxiliary contact ratings are provided for DC loads: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. No auxiliary switch block is included as standard.

Dimensions are 55 mm wide, 114 mm high, and 174 mm deep. Wire capacity for main contacts is 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²) solid or stranded.
