ABB KSE363TPN 63A 3-Pole Enclosed Switch Disconnector – IP65

The ABB KSE363TPN (order code 2CMA144580R1000) is a 63A, 3-pole enclosed switch-disconnector with an IP65 die-cast aluminium enclosure, rated 45A / 22kW for AC-23 motor-switching duty. It provides safe, visible on-load isolation for maintenance and lockout, and is built to withstand the dust, heat and humidity of outdoor installations across the UAE, Saudi Arabia and the wider GCC. For panel builders and pump-panel manufacturers it works equally well as a local motor isolator beside the equipment or as a lockable main switch inside a control enclosure.

Applications & Compatibility

• Local isolator and lockout point beside pumps, fans, motors and machinery for safe maintenance.
• Main switch or incomer isolator inside control panels and pump-control panels.

• Water and wastewater, HVAC plant, construction, oil and gas and building services across the UAE and KSA.
• 3-pole plus neutral (TPN) configuration suited to 4-wire and 5-wire three-phase systems.
• Isolation device only — install downstream of an MCB, MCCB or fuse for short-circuit and overload protection.

Why Buy From Electrical Junction

Electrical Junction stocks genuine ABB isolators in the UAE and exports across Saudi Arabia and the GCC, backed by a direct sourcing pipeline through our Mumbai operation (MAS Global Enterprises) for competitive pricing and reliable restocking. Utilization-category and sizing questions — the 63A versus 45A AC-23 point that trips up many buyers — are answered directly by our engineer before dispatch, so you order the right isolator for the actual load, not just the nameplate current.

Frequently Asked Questions

Is the ABB KSE363TPN rated 63A or 45A?

The ABB KSE363TPN is a 63A switch-disconnector, and both figures are correct for different duties. It carries 63A as its conventional thermal and AC-22A rating (mixed and resistive loads), and is rated 45A / 22kW for AC-23A duty (switching a running motor). Size it on the 63A figure for isolation and general loads, and on the 45A / 22kW figure when it directly switches a motor.

What does TPN mean on the KSE363TPN, and is the neutral switched?

TPN stands for Triple Pole and Neutral. The KSE363TPN switches the three phases and includes a neutral (N) terminal plus an earth (PE) terminal, making it suitable for 4-wire and 5-wire three-phase systems. The three phase poles are switched while the neutral is provided as a terminal connection.

Is the KSE363TPN suitable for outdoor installation in the UAE and Saudi Arabia?

Yes, the KSE363TPN is rated IP65 in a die-cast aluminium (silumin) enclosure, protecting it against dust ingress and low-pressure water jets. This makes it suited to outdoor and washdown installations across the UAE, Saudi Arabia and the wider GCC, including desert dust and high humidity.

Can the ABB KSE363TPN be used as a local motor isolator?

Yes, the KSE363TPN is rated 45A / 22kW for AC-23A motor-switching duty and is commonly used as a local isolator beside pumps, fans and motors. Its cover is interlocked and the handle can be padlocked in the OFF position for safe lockout during maintenance.

Does the KSE363TPN provide short-circuit or overload protection?

No, the KSE363TPN is a switch-disconnector (isolator) that provides safe on-load isolation only, not automatic protection. It must be installed downstream of an MCB, MCCB or fuse that provides short-circuit and overload protection for the circuit.

How does the KSE aluminium enclosure differ from ABB BW plastic isolators?

The KSE363TPN uses a rigid die-cast aluminium (silumin) enclosure with a front-operated black round handle, giving high mechanical strength for harsh environments. ABB's BW-series isolators use a rigid polycarbonate (plastic) enclosure and are typically side-operated. Both are IP65, so the choice depends on whether metal ruggedness or a lighter plastic housing suits the installation.
