Key Features
-
High-Current Load Handling
The internal contacts support a 50A continuous current rating for inductive loads. -
Auxiliary Contact Configuration
- Integrated 1 Normally Open (NO) contact
- Integrated 1 Normally Closed (NC) contact
- Supports logic feedback to control systems
-
Arc Suppression Chamber
The design includes specialized chutes to extinguish electrical arcs during high-voltage switching. -
DIN Rail Compatibility
Standard 35mm rail mounting facilitates rapid installation in modular distribution boards.
The 3-pole architecture ensures simultaneous phase switching for three-phase motors. Silver alloy contact tips reduce electrical resistance during operation. This material choice prevents contact welding during high-inrush current events. The coil operates on a standard 220V/240V AC supply. It maintains a strong magnetic hold to prevent chatter or vibration. The housing consists of flame-retardant thermoplastics. This material protects internal components from dust and debris.
Engineers can utilize the unit for direct-on-line (DOL) starting of motors. It functions effectively in star-delta starter configurations. The mechanical life exceeds several million cycles under normal operating conditions. Additionally, the terminal design features deep screw wells for secure wire termination. These terminals accommodate various wire gauges for flexible wiring options. The compact footprint allows for high-density mounting inside control panels. Each unit undergoes rigorous testing to meet international safety standards. This ensures consistent performance in HVAC systems and water pump controllers.
Maintenance teams appreciate the accessible terminal markings for fast troubleshooting. The electromagnetic coil is replaceable to extend the service life of the frame. Consequently, the unit provides a cost-effective solution for long-term infrastructure projects. It handles frequent start-stop cycles without significant degradation of the contact surfaces. The 50A rating provides a safety margin for 45A motor applications.

Installed this in a control panel for a borehole pump in Kikuyu. The build quality of the Powermax 50A is solid and it handles the starting current without any issues. Good value for money compared to the more expensive brands.
Eng. Otieno (verified owner) –
The 3-pole 50A unit is quite reliable for heavy duty AC-3 applications. The 220V coil is responsive. Only wish the terminal screws were slightly larger for easier wiring with thick cables, but otherwise a very sturdy piece of kit.
