Suitable for indoor use.
Managing electrical circuits safely requires robust and dependable isolation devices. The 20A, 4-Pole Rotary Isolator is specifically engineered to provide a secure method of completely disconnecting power to three-phase equipment running on AC supply. Its 20-amp rating makes it a perfect fit for a wide range of machinery, HVAC systems, and industrial motors, ensuring maintenance personnel can work without risk of unexpected energization. The four-pole configuration allows simultaneous switching of all three live phases and the neutral line, offering comprehensive circuit isolation in a single, decisive action.
Built with a focus on durability, this isolator features a high IP65 rating, meaning it is fully protected against dust ingress and low-pressure water jets from any direction. This rugged construction makes it suitable for demanding environments, including workshops, manufacturing floors, and outdoor installations. The rotary action provides clear visual confirmation of the "On" or "Off" status, an essential safety feature. Whether you are upgrading existing controls or installing new equipment, this isolator combines functional safety with the long-term reliability required for continuous operation.
Complete 4-Pole Isolation: Switches three phases and neutral simultaneously for total circuit disconnection.
High IP65 Protection: Dust-tight and protected against water jets, suitable for indoor and outdoor use.
Robust 20A AC Rating: Designed to handle continuous AC loads up to 20 amps safely.
Clear Rotary Action: Provides tactile and visual indication of the switching state (On/Off).
Versatile Application: Ideal for motors, HVAC units, pumps, and industrial control panels.
Durable Build: Constructed to withstand harsh industrial environments.

1. What does "4 Pole" mean on this isolator?
A 4-pole isolator means it can switch four separate circuits simultaneously. In a typical three-phase system, it disconnects all three live phases (L1, L2, L3) and the neutral (N) line at the same time, ensuring the entire system is fully isolated.
2. Can this rotary isolator be used outdoors?
Yes, it is rated IP65, which makes it dust-tight and protected against low-pressure water jets. This allows for safe outdoor installation, though it should not be submerged.
3. Is the 20A rating for AC or DC use?
This model is specifically rated for AC (Alternating Current) applications up to 20 amps at 415V. It is not designed for DC (Direct Current) circuits.
4. What type of equipment is this isolator suitable for?
It is ideal for isolating three-phase equipment such as small industrial motors, compressors, ventilation fans, commercial ovens, and air conditioning units that draw up to 20A.
5. Does the isolator come with a padlockable handle?
The provided technical information does not specify a padlockable feature. For lockable isolation requirements, you may need to check with the supplier or consider an external lockable enclosure.
