Why choose the Schneider Resi9 XE 2P 50A curve C circuit breaker?



1. C curve: the perfect balance for mixed installations

The C tripping curve offers a magnetic threshold of 5 to 10 times the rated current (i.e. 250-500A for a 50A). This characteristic guarantees:

  • ✅ Effective protection against short-circuits: instantaneous tripping from 250A
  • ✅ Inrush current tolerance: avoids nuisance tripping when starting heat pumps, compressors, transformers, etc.
  • ✅ Versatility: suitable for resistive loads (heating), inductive loads (motors) and capacitive loads (photovoltaic inverters).



2. 2P configuration: secure bipolar breaking

The protected 2-pole circuit-breaker provides :

  • Simultaneous phase + neutral breaking (single-phase): enhanced safety for maintenance, complete isolation of the circuit
  • 2-phase breaking (two-phase 400V): protection of two-phase loads (certain heat pumps, industrial machines)
  • Standards compliance: meets Belgian and European requirements (RGIE, NF C 15-100)



3. 3kA breaking capacity: suitable for residential/tertiary use

The 3000A (3kA) breaking capacity is perfectly sized for :

  • ✅ S tandard residential installations: typical short-circuit current 1.5-2.5kA at end of line
  • ✅ Branch circuits downstream of the main switchboard: protection of sub-divisional switchboards
  • ✅ Domestic photovoltaic installations: AC inverter protection 3-12kW

💡 Good to know: For installations with high short-circuit currents (close to transformers, large subscriptions), give preference to the iC60N (6kA) or iC60H (10kA) ranges.



4. 50A capacity: high-power circuits

With 50A @ 230V = 11.5 kW of protected power, this circuit-breaker protects :

  • 🔋 Photovoltaic inverters up to 12 kW AC (e.g. Deye SUN-12K-SG04LP3, Huawei SUN2000-12KTL-M2)
  • ⚡ 1 1 kW single-phase EV charging stations (Type 2 accelerated charging)
  • 🌡️ Heat pumps 8-10 kW electric (thermal output 25-35 kW)
  • 🔥 High-power central heating (electric radiators, underfloor heating)

⚠️ Warning: Always check cable cross-section, line length and voltage drop. For precise calculations, use our cable section calculator.



Installation advice

  • DIN rail mounting: clip the circuit breaker onto a standard 35mm DIN rail, 4 modules wide (36mm).
  • Wiring: use rigid conductors (H07V-R/U) or flexible conductors with ferrules (H07V-K + crimp ferrules)
  • Minimum cross-section: 10 mm² copper for 50A (depending on length and installation method, consult RGIE/NF C 15-100)
  • Tightening torque: 2 N.m (check with a torque screwdriver)
  • Identification: clearly label the protected circuit (e.g. "PV Inverter", "VE Wallbox", "PAC")
  • Ventilation: allow 10-15mm spacing above/below for heat dissipation





🌞 Focus: Integration in photovoltaic installations
