Power limiter Eti-Polam ETIMAT T 1P 10A (MPN 002181072)

The Eti-Polam ETIMAT T 1P 10A is a single-pole power limiter designed to restrict the electrical load of a single-phase circuit to 10 A. Intended for installation in residential or light-commercial distribution boards, this device helps manage available power, prevent tripping of main fuses, and coordinate with other protective equipment. The limiter operates by monitoring current consumption and disconnecting the load or signaling when the preset threshold is exceeded, enabling predictable power management in installations with limited supply capacity.

Advantages

The unit provides precise load limitation for a single-phase circuit up to 10 A, reducing the risk of overloading supply lines or main protection devices. Its compact single-pole design allows straightforward integration into standard DIN-rail distribution boards. The device supports coordination with upstream protective devices and other load-management components, helping maintain continuity of service and preventing nuisance trips. Installation and configuration are compatible with common residential and small commercial wiring practices.

Suitable for

• Residential distribution boards where total available current must be limited
• Small commercial or light-industrial panels with single-phase circuits
• Load management in premises with limited mains supply or shared supply constraints
• Coordinating with circuit breakers and residual current devices to prevent main fuse trips

When it may not be suitable

This single-pole 10 A limiter is not intended for three-phase installations or where higher continuous currents are required. It may not be suitable for circuits supplying large appliances or motors that demand currents above the specified 10 A limit. For applications requiring dynamic power management, remote telemetry, or advanced programmable control, consider devices specifically designed with those features.

Key specifications

• Poles: single-pole (1P)
• Rated limiting current: 10 A
• Intended use: single-phase circuits
• Mounting: DIN-rail compatible for distribution boards
• Function: automatic load limiting/overload prevention

How to use

Install the power limiter on the DIN rail inside the distribution board according to local wiring rules and the manufacturer's installation instructions. Connect the device in series with the load conductor of the single-phase circuit to be limited. After wiring, verify polarity and tighten terminals to the recommended torque. Commission the circuit by gradually applying load and confirming that the limiter interrupts or signals at the expected threshold near 10 A. Coordinate settings and protections with upstream breakers and any residual current devices to ensure proper selectivity.

What to consider before purchase

• Confirm that a single-pole 10 A limit meets the load requirements of the circuit and connected equipment
• Verify compatibility with the existing distribution board (DIN-rail space and terminal types)
• Ensure the device's functional behaviour (disconnect or signal) aligns with your power-management strategy
• Check local electrical codes for required coordination with protective devices and qualified installation

Usage recommendations

Use the ETIMAT T 1P 10A in conjunction with correctly rated upstream circuit breakers and residual current devices. Perform a load survey before installation to confirm that typical operating currents are below the 10 A threshold, and schedule a functional test after installation to validate reliable operation.
