The WAC4P63 is a heavy-duty 4 Pole 63 A modular contactor designed for high-load control in EV chargers, HVAC systems, industrial lighting banks and automation circuits. Mounts directly on a 35 mm DIN rail inside modular enclosures or consumer units where quiet, reliable switching is essential.
Offering long mechanical life and low-noise coil performance, the WAC4P63 is suitable for both single and three-phase control applications. Fully tested to BS EN 61095 and BS EN 60947-4-1, it meets the requirements of the 18th Edition Wiring Regulations (BS 7671).
Installer Tip: Choose the 63 A model for large three-phase lighting or plant control systems where quiet operation and neutral disconnection are required. Ensure sufficient airflow around the unit for thermal management under continuous load.
- Silent-coil design for noise-sensitive installations
- 4-pole configuration for three-phase or multi-circuit control
- DIN-rail mount for fast installation and maintenance
- 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) |

| WAC4P40 | 4 Pole Modular Contactor | 40 A |
| WAC4P63 | 4 Pole Modular Contactor | 63 A |
| WAC4P100 | 4 Pole Modular Contactor | 100 A |
| WAC4P125 | 4 Pole Modular Contactor | 125 A |
For single-phase switching, see our 2 Pole Modular Contactors or Rotary Isolators.
What is the WAC4P63 used for?
It switches and controls high-load three-phase or multi-circuit systems up to 63 A, such as lighting banks, EV chargers and HVAC equipment.
Does it allow neutral disconnection?
Yes – the 4-pole layout supports full neutral isolation when required for testing or maintenance.
Is the WAC4P63 quiet in operation?
Yes – it features a silent coil for residential and commercial use where noise control is important.
Can it be combined with protection devices?
Yes – use with RCBOs, RCDs and SPDs to ensure full protection and compliance.
Does it meet UK standards?
Fully compliant with BS EN 61095 and BS EN 60947-4-1, meeting the 18th Edition Wiring Regulations (BS 7671).
