## Description

Ensure optimal electrical protection with this high-quality Type-A RCD, designed for both residential and industrial use. This double-pole, din rail-mounted RCD provides reliable protection against electrical faults by detecting leakage currents, helping to prevent shock hazards and equipment damage. With options for multiple amperages and sensitivities, this RCD is versatile and suitable for various applications. Built to meet stringent safety standards, it ensures smooth and safe electrical operations, making it a trusted choice for electricians and DIY installers alike. In the UK, regulations require Type A RCDs for circuits with devices that produce pulsating DC currents, such as modern appliances and EV chargers, while Type AC RCDs are no longer recommended for new installations due to their limited protection.

## Features

- 16 Amp, 30mA, 2 Pole, Type-A RCD. Use a standard RCD if it is the only RCD in the circuit or protecting a single final circuit.
- In the UK, regulations require Type-A RCDs for circuits with devices that produce pulsating DC currents, such as modern appliances and EV chargers, while Type AC RCDs are no longer recommended for new installations due to their limited protection.
- Type A RCD: Provides reliable protection against both AC and pulsating DC leakage currents.
- Double Pole Design: Ensures complete disconnection from the electrical circuit for maximum safety. With the Neutral pole on the left.
- Din Rail Mounted: Quick and secure installation on standard DIN rails for both residential and industrial use.
- Enhanced Safety: Detects leakage currents to prevent electric shocks and equipment damage.
- Wide Application: Ideal for modern appliances and electronics that generate DC fault currents.
- Compliant with Standards: Meets IEC61008-1 / EN61008-1 safety standards for electrical installations in the UK.
