BSR 20A Double Pole Grey Switch
The Powermax BSR 20A Switch facilitates safe control over high-wattage water heating appliances in diverse electrical installations. This specific unit functions as a double pole isolation device to ensure complete circuit disconnection. It severs both the live and neutral paths to protect users and maintenance personnel from residual voltages. The grey finish integrates well with modern industrial or residential interior designs. This component belongs to the Powermax BSR series, known for durability and compliance with international safety standards.
The internal switching mechanism utilizes high-conductivity copper alloy contacts to minimize electrical resistance. Lower resistance reduces heat generation during periods of continuous high-load operation. This engineering choice extends the operational life of the internal components significantly. The switch handles a steady current of 20 amperes at a standard 250V AC frequency. It manages the inductive and resistive loads typical of domestic and commercial water heaters. Engineers specify these units for their robust mechanical performance over thousands of cycles.
The exterior housing consists of high-impact polycarbonate material with flame-retardant properties. This material choice ensures the device remains structurally sound under thermal stress or accidental impact. The grey pigmentation is molded into the plastic to prevent fading or chipping over time. A clear neon indicator lamp is integrated into the faceplate to signal when the circuit is active. This visual aid improves user safety and helps prevent unnecessary energy consumption by identifying active appliances.
Installation efficiency is a priority in the design of this 20-ampere controller. The rear housing features large, angled terminal entries to simplify cable insertion in cramped mounting boxes. These terminals accommodate multiple conductors, allowing for loop-in wiring configurations where necessary. Captive terminal screws remain attached to the housing to prevent loss during the mounting process. The unit fits standard 86mm x 86mm single-gang back boxes. It includes matching screw covers to provide a clean and professional appearance after installation.
For large-scale projects, these units come in bulk packaging of 100 pieces per carton. This logistics-friendly configuration suits procurement managers handling high-volume residential developments or commercial fit-outs. Each switch undergoes factory testing to verify insulation resistance and dielectric strength. The BSR series adheres to BS EN 60669-1 requirements for low-voltage switches. This compliance ensures the hardware meets the safety expectations of local building codes and electrical regulations.

It does the job well and the double pole safety is essential. However, the grey is a bit darker than it looks in the photos. Also, the switch button is quite stiff to press initially, though it seems to be loosening up with use. Sturdy unit nonetheless.

Picked this for a bathroom renovation in Syokimau. Most switches are white, so this grey finish really stands out and matches the tiles perfectly. The double pole action feels very solid, not like those cheap ones that spark. It’s been running our 3kw heater for a month now with no issues.

Good quality switch. The material feels durable and the indicator light is clear enough to see from across the room. Delivery to Thika was fast, arrived the next day. Giving 4 stars only because the screws in the box were a bit short for my deep mounting box, but the switch itself is top notch.

I’ve been using Powermax products for my electrical projects in Ruaka and they rarely disappoint. This 20A double pole switch is perfect for the larger storage tanks. The grey finish is sleek and modern. It handles the load without heating up, which is the most important thing for a water heater circuit. Highly recommended for anyone doing a modern build.

We installed these in our new office kitchenette for the under-sink heaters. The Powermax BSR range looks professional and the grey doesn’t show fingerprints like the white ones do. Very satisfied with the build quality.
