ABB OT1000E03P 3-Pole 1000A Switch-Disconnector
The ABB OT1000E03P is a 3-pole, front-operated switch-disconnector rated for 1000A, designed for base mounting in low voltage distribution boards and panels. Fitted with a black IP65-rated handle and shaft, and supplied with a terminal bolt kit, it is built for reliable isolation duty in demanding industrial and commercial installations across the UAE.
Key Features
- 3-pole switch-disconnector rated for 1000A operational current (AC-23A) across 380–690V applications
- Black IP65-rated handle and shaft for reliable sealed manual operation, with terminal bolt kit included for straightforward installation
- High rated insulation voltage of 1000V and rated impulse withstand voltage of 12kV for robust dielectric performance
- Rated short-time withstand current (Icw) of 50kA for 1s, suitable for high fault-level panel applications
- Genuine ABB quality — manufactured to IEC 60947-3 standard

FAQ
-
Is this an MCB or an isolator?
It's an isolator (switch-disconnector), not an MCB. It has no overload or short-circuit protection — it only provides a manual on/off disconnect, and should be paired with separate MCBs or RCCBs for circuit protection.
-
What does 3-pole mean for this isolator?
3-pole means it switches all three phases on a three-phase supply.
-
Where should this isolator be installed?
Typically as the main incoming switch or a local isolation point ahead of the MCBs/RCCBs in a distribution board, so the whole board (or a section of it) can be isolated for maintenance without needing to trip individual breakers.
-
Can I install this myself?
No. This is trade-only distribution board equipment and must be installed and connected by a licensed electrician in accordance with local wiring regulations.
-
Can this isolator be used to switch a live circuit under load?
Isolators rated for on-load switching can do this within their utilisation category, but check the specific AC rating in the Technical Specifications table — an isolator is not a protective device and should not substitute for a circuit breaker.
