Water fault circuit breakers – automated shut-off for maximum protection

Tollco’s Water fault circuit breakers are designed to reliably detect, limit and stop water leaks before they cause costly damage. Using motorized valves, smart sensor technology and easy-to-install control modules, the systems shut off the water supply at exactly the right moment – in homes, workplaces or public facilities.

They are easy to install, highly dependable and form an effective complement to Tollco’s passive leak-prevention systems.

Products – Water fault circuit breakers for appliances

Tollco’s Water fault circuit breakers are developed for pressurized water connections such as dishwashers, washing machines, coffee machines and other equipment where even small leaks can cause serious damage. The system automatically shuts off the water and activates an audible alarm when moisture is detected. A motorized valve is installed on the water line, and sensors are placed beneath the protected appliance.

Water fault circuit breaker – Wired

A reliable, straightforward variant with a cable-connected moisture sensor. When a leak occurs, the water is shut off immediately and a clear audible warning is triggered. The unit plugs directly into a wall outlet and is suitable for most pressurized appliances in homes and professional environments.

Benefits:

Instant and secure shut-off
Stable and interference-free wired sensor
Easy installation
Available with multiple valve configurations (DN15 & DN20)

Water fault circuit breaker – Wireless

A flexible solution capable of monitoring multiple areas simultaneously. Each unit can connect up to 16 wireless detectors, ideal for larger spaces or multiple appliances. Sensors can be placed beneath appliances or inside drip trays. When moisture is detected, the system quickly shuts off the water and triggers a loud alarm.

Benefits:

Supports up to 16 wireless detectors
Optional cotton or tape-based sensors
Motorized shut-off valve on the water line
Simple plug-in installation

Products – Water fault circuit breakers for public facilities

Tollco’s public-environment Water fault circuit breaker is engineered specifically for schools, sports facilities, locker rooms and other locations with increased vandalism risks. By linking water supply and lighting to presence detection, the system prevents flooding caused by deliberately blocked sinks, damaged fixtures or taps left running.

Principle:
Presence = water on
No presence = water off

Water fault circuit breaker – Public environments

This system combines a motion detector with motorized valves and lighting control. When someone enters the room, both water and lighting are activated. When the room is empty, a configurable delay time starts before water and lighting are switched off.

Features & benefits:

Prevents vandalism-related water damage
Presence-controlled water + lighting
Adjustable delay time
Energy-efficient (lights turn off automatically)
Motor valves (12 VDC) with manual operation
Two valves included, optional third valve
Significant reduction of damage costs
Operating voltage: 230 VAC

Examples of incidents prevented:

Sinks filled and blocked to cause overflow
Toilets or urinals damaged or deliberately clogged
Running taps left unattended
