At a Glance. Socomec's product lines solve distinct problems in industrial and renewable power systems: MASTERYS IP+ is the online double-conversion UPS for mission-critical AC loads; MAS BAT / MAS DIS BAT is the modular battery storage cabinet for energy buffering and peak shaving; SIRCO PV is the DC load-break switch for photovoltaic strings up to 1000 Vdc / 1500 Vdc; ATyS S is the automatic transfer switch for source-changeover between two AC supplies; and the FUS GG / CDE FE lines cover fused switch-disconnectors and distribution. This guide maps each product to its typical use case and gives a decision flow.

2. Decision Guide — Which Socomec Product Fits Your Application?
- Critical AC load needs ride-through for power cuts / dips? → MASTERYS IP+ online UPS (30 kVA 3/3 for IT rooms, 10 kVA for smaller control cabinets).
- Need extended runtime beyond standard battery? → Add MAS BAT (MAS DIS BAT-LL) or MAS BAT-LL (2x22x92AH) long-life shelf.
- PV array, must isolate DC string under load? → SIRCO PV (4X600A 1000 Vdc) — DC-rated, breaks load safely.
- Two AC sources (utility + generator), automatic changeover? → ATyS S (4X80A 230V); size up to 1600 A with same family.
- Local AC isolation in a motor control centre? → CT LBS (4P 160A IP65) — visible-break, padlock-able.
- Short-circuit protection on a branch? → FUS GG cylindrical HRC fuse (10x38 20A), in combination with a fused switch-disconnector.
- Distribution panel needs fused switch? → CDE FE (4X D-G) with HRC fuse carriers.
3. UPS Sizing — One Line of Practical Guidance
Match UPS apparent power (kVA) to the sum of load kVA, then apply a 1.2–1.5 derating factor for inrush and future growth. A MASTERYS IP+ 30 kVA comfortably feeds a 20 kW IT rack plus an 8 kW control cabinet. For longer autonomy, add MAS BAT in the same footprint family; the SOCOMEC sizing tool gives exact cabinet combinations.
4. PV DC Switching — Why SIRCO PV and Not a Standard AC Switch
Standard AC switches are not rated for switching a DC arc, which is much harder to extinguish. The SIRCO PV series uses pole doubling (4 poles in series for 1000 Vdc) and arc-quenching chambers tested to IEC 60947-3, DC-21B / DC-PV2. Using an AC switch on a PV string risks contact welding and fire. Always check the DC-PV utilization category on the nameplate.
5. Quick FAQ
Q: Can MASTERYS IP+ run in parallel for redundancy?
Yes, up to 6 units in parallel with shared static-bypass and load-share bus (MASTERYS IP+ "XR" configuration).
Q: Are MAS batteries hot-swappable?
Yes, in modular configurations with individual breaker isolation. Refer to the MAS installation manual for exact steps.
Q: ATyS S 80 A — can it switch a generator in < 1 s?
Yes, the controller transitions in < 200 ms typical when both sources are healthy.
