The WAC4P32 is a versatile 4 Pole 32 A modular contactor providing silent, dependable switching for lighting banks, HVAC systems, EV chargers and building automation. It mounts directly on a 35 mm DIN rail and fits modular enclosures or consumer units where multi-pole control is required.
Designed for both single- and three-phase applications, the WAC4P32 offers noise-free operation and long mechanical life. It is tested to BS EN 61095 and BS EN 60947-4-1 for safe switching of resistive and inductive loads under the 18th Edition Wiring Regulations (BS 7671).
Installer Tip: Select the 32 A model for three-phase control systems or linked lighting banks requiring neutral disconnection. Combine with appropriate RCBO or RCD protection for compliance and safety.
- Silent-coil design for residential and commercial use
- 4-pole configuration for three-phase or multi-circuit control
- DIN-rail mount for fast installation in boards and enclosures
- Rated for AC-7a (resistive) and AC-1 (inductive) loads
- Complies with BS EN 61095 and BS EN 60947-4-1
Available Variants (4 Pole Range):
| Part Code | Description | Rated Current (A) |
