The WAC4P25 is a reliable 4 Pole 25 A modular contactor designed for quiet, dependable switching across multi-circuit lighting, HVAC, EV and automation systems. Compact and DIN-rail mountable, it fits neatly into modular enclosures and consumer units where noise control and compliance are important.
Tested to BS EN 61095 and BS EN 60947-4-1, the WAC4P25 provides safe, long-life operation under the 18th Edition Wiring Regulations (BS 7671). It’s suited to both single and three-phase circuits requiring multi-pole isolation or neutral disconnection.
Installer Tip: Choose the 25 A 4-pole model for multi-circuit lighting or control systems needing neutral disconnection. Keep coil leads away from signal wiring to avoid induced voltage on automation loops.
- Silent-coil design – ideal for residential and commercial use
- 4-pole configuration for multi-circuit or three-phase control
- DIN-rail mount for fast fit into boards and enclosures
- Compatible with AC-7a and AC-1 load categories
- Complies with BS EN 61095 and BS EN 60947-4-1
Available Variants (4 Pole Range):
| Part Code | Description | Rated Current (A) |
