Legrand 049926 DX3 Ρελέ προστασίας διαρροής 2P 25A 30mA Τύπου A

For installations where protection against earth leakage currents is non-negotiable, the Legrand 049926 DX3 RCCB stands out with its Type A sensitivity, detecting both AC and pulsating DC residual currents. Unlike basic AC-only devices, this 2-pole unit ensures reliable disconnection in modern circuits with electronic loads, preventing dangerous shocks and fire risks. Its 25 A rated current and 30 mA trip threshold make it a versatile choice for residential and commercial distribution boards.

Highlights

• Type A residual current protection (AC and pulsating DC)
• 2-pole design, 2 modules wide (35 mm) for DIN rail mounting
• Rated current 25 A, residual current 30 mA
• 6 kA conditional short-circuit rating
• Complies with EN 61008-1

In daily use

Installed on a standard DIN rail, the DX3 breaker fits neatly into any distribution board, occupying just two modules. Screw terminals accept rigid conductors from 1.5 to 25 mm² and flexible from 1.5 to 16 mm², ensuring secure connections. The device operates reliably across a wide temperature range from -25°C to +60°C, and its IP20 terminal protection (IP40 front when enclosed) suits typical indoor environments. The instantaneous tripping characteristic means faults are cleared without delay, minimizing exposure to hazardous currents.
