Flood sensor relay ZAMEL PZM-10 (SZH-03 probe) 1P 16A 2500VA 230V AC

ZAMEL PZM-10 with SZH-03 probe is a compact flood sensor relay intended to detect the presence of water and switch a single-pole output. The device monitors contact with the external probe and provides automatic switching of a connected circuit at mains voltage. Rated for 1 pole, 16 A and 2500 VA at 230 V AC, the relay is designed for control of pumps, alarms or valve actuators where reliable disconnection or activation is needed upon water detection. The compact enclosure and simple probe connection make the unit suitable for installation in basements, utility rooms and technical spaces.

Advantages

The flood sensor relay offers a straightforward electromechanical switching solution with a defined 16 A load capacity and 2500 VA switching power at 230 V AC. Its single-pole output simplifies integration into existing electrical circuits while the external SZH-03 probe allows flexible placement to detect water at low points. The product delivers automatic response to water contact without requiring complex configuration, and its rated electrical parameters enable direct control of common pumps and alarm devices.

Suitable for

• Automatic control of submersible or surface pumps
• Activation of audible or visual alarm systems on water detection
• Control of valve actuators to stop water supply
• Protection of basements, utility rooms and equipment rooms
• Integration into simple building management or safety circuits

Key specifications

• Operating voltage: 230 V AC
• Contact configuration: single-pole switching
• Rated current: 16 A
• Rated switching power: 2500 VA
• Probe type: external SZH-03 water detection probe
• Intended function: automatic switching on water contact

How to use

Mount the relay enclosure in a dry, accessible location near the area to be monitored and route the SZH-03 probe to the low point where water detection is required. Connect mains supply and the controlled load according to local wiring standards, observing the single-pole contact arrangement. Place the probe so that it contacts water when flooding occurs; when the probe senses water the relay will switch the output to activate or deactivate the connected device. Ensure power is isolated during installation and follow applicable electrical safety rules.

Usage recommendations

For reliable operation, position the SZH-03 probe at the typical lowest water accumulation point and check probe and wiring periodically for corrosion or damage. Use the relay within its rated current and switching power limits and, where necessary, add an appropriate contactor or protective device when controlling inductive loads such as large pumps. Install according to local electrical codes and consider a backup alarm or monitoring system for critical installations.
