ABB 40A 3P Weather Proof Isolator

Key specs include a 40A current rating, 3 poles, a weatherproof design, and corrosion-resistant construction. It is UL and CSA approved, making it compliant with common safety standards for residential and commercial use.

Ideal for protecting circuits in residential service panels, outdoor equipment, and commercial electrical installations where reliable isolation and weather resistance are important.

Before installation, switch off power and wear appropriate PPE. Mount the unit to a suitable panel or enclosure, connect the three input/output terminals per your wiring design, securely fasten all connections, and ensure the enclosure remains weatherproof after installation. Then verify the circuit functions correctly with suitable testing equipment.

Use appropriate conductor sizes and compatible terminals for a 3-pole configuration. Mount the isolator in a suitable enclosure or panel that maintains its weatherproof rating, and ensure all connections are tight and protected from moisture ingress.

Its weatherproof design and corrosion-resistant housing are intended to protect internal components from moisture, dust, and other environmental contaminants, making it suitable for outdoor installations as well as indoor use.
