VDL01 RCBO Circuit Breaker — 2P/4P Adjustable Residual Current Protection (up to 90A)
rcbo circuit breaker VDL01 with 2P/4P options and adjustable current pairs (5/15A → 60/90A), designed for mains/feeder protection.
Normal & Type S (time-delay) residual protection with IΔn 300 mA / 500 mA, coordinated selectivity for upstream devices.
Icn 3 kA, 230/240 V & 400/415 V, digital current display, anti-tamper design; built to NF C 61450 / NF C 62411 / IEC 61009.
rcbo circuit breaker VDL01 is a two- or four-pole adjustable device combining residual-current and overcurrent protection for mains and feeder circuits, with selectable Normal and Type S (time-delay) characteristics.
Overview
VDL01 integrates residual-current and overcurrent protection into a compact 2P/4P form.
It features adjustable current pairs to match upstream/downstream coordination and
offers Normal and Type S (time-delay) residual functions with higher
sensitivities (IΔn 300 mA / 500 mA) suitable for main/feeder selectivity.
A digital current display and anti-tamper design improve on-site setting and security.

Applications
- Mains and feeder circuits requiring selective residual protection (Type S)
- Commercial and public buildings with coordinated upstream devices
- Three-phase distribution where 4P selectivity and higher IΔn are needed
- Panels needing adjustable current pairs for field tuning
Standards & Compliance
Designed in accordance with NF C 61450, NF C 62411, and IEC 61009. Check local codes for selectivity and discrimination requirements.
FAQ
What does Type S mean on VDL01?
Type S is a time-delay residual function that helps achieve selectivity with downstream RCD/RCBOs, reducing nuisance trips on mains/feeder circuits.
How do the adjustable current pairs work?
You can select among 5/15, 10/30, 15/45, 30/60, and 60/90 A pairs to match the protected feeder and upstream device, using the built-in digital display to verify settings.
When should I choose 4P over 2P?
Use 4P for three-phase systems or when neutral switching and full four-pole isolation are required; 2P fits single-phase feeders.
Which IΔn should I use?
VDL01 offers 300 mA and 500 mA suited for upstream selectivity. Choose per local codes and coordination studies.
