🧰 Typical Application Scenarios

AVAC: Control of fans, electric heaters and water pumps

Industrial automation control cabinets: PLC output power expansion

Switching high-power circuits for air compressors, packaging machinery and conveyors

High-power load switches inside control cabinets

⚠️ Selection & Notas de instalação

Derating requirement: When multiple relays are mounted side-by-side tightly, rated contact current is derated to 25A; a 13mm gap between relays is required to reach full 30A rating.
Para cargas indutivas (motores, bobinas do contator), surge suppression components are recommended in parallel to extend contact life.
Base must be RPZF2, RXM small relay bases cannot be used interchangeably.

Schneider RPF2BBD (2CO 30A, CC24V, Sem LED) Cenários de aplicação

Posicionamento central: Plug-in high-power relay for PLC output amplification, 2Contatos CO, 24Bobina VCC, max 30A (with gap), derated to 25A when side-by-side installed. Base RPZF2, Trilho DIN / panel dual mounting, wide temperature range -40~+55℃, suitable for high-power load switching inside industrial cabinets.

AVAC & Building Air Conditioning (Aplicação mais comum)
Central air handling units (AHU): Control of fans, electric heating sections, humidifiers and condensate pumps
Heat pump units & constant temperature/humidity control cabinets: Auxiliary compressor circuits, high-power actuating for water valves
Fresh air purification units: Start/stop of large supply & exaustores, DO point amplification for building BA systems

Vantagens: 24VDC coil matches DDC controllers; 2CO contacts can control main power circuit and feedback signal simultaneously. Wide temperature range suits machine rooms and outdoor cabinets.

Industrial Automation Control Cabinets
PLC digital output amplification: PLC DO points normally rated 0.5~2A. RPF2BBD drives 30A resistive/inductive loads and isolates strong/weak current to protect PLC modules. One set of 2CO contacts for main load, the other for passive status feedback to PLC DI.
Máquinas de embalagem, linhas transportadoras, equipamento de montagem: Control of heavy-duty conveyor belts, drying heating tubes and large solenoid valve banks
Control cabinets for air compressors & refrigeradores: Ventiladores de resfriamento, drain pumps and heater on/off
Hydraulic/pneumatic stations: Auxiliary control of high-current solenoid directional valves and hydraulic pumps
Automação Predial
Building distribution panels: High-power lighting circuits, exaustores, sewage pumps and fire supply air fans
UPS machine room power cabinets: Fãs, heaters and dehumidifier control
Commercial equipment control cabinets: Commercial ovens, drying equipment and high-power resistive heating loads
Nova Energia & Energy Storage Auxiliary Systems
Energy storage BMS cabinets: Switching of cooling fans, cabin heaters and dehumidification loads
Auxiliary loads of small PV combiner boxes: Fans and anti-condensation heating circuits
Equipamento Especial (Wide Temperature Advantage)
Onboard / equipamento móvel, construction machinery electrical cabinets: -40℃ cold start, withstand wide temperature shock
Marine auxiliary machinery control cabinets (select with marine certifications): Cabin fans and pump loads

✅ Selection & Dicas de aplicação (Scenario Reminders)

Load types: Resistive loads preferred. For inductive loads such as motors and contactor coils, supressão de surto (Amortecedor RC / diodo / varistor) deve ser montado; otherwise contact service life will drop sharply.
Current derating: When multiple RPF relays are closely mounted side-by-side, use 25A as rated current; reserve ≥13mm gap between relays to achieve full 30A.
2CO (DPDT) recurso: One contact set for main power circuit, the other for passive status feedback. This is the key advantage over RPF2ABD (2NÃO), ideal for automation systems requiring relay status acquisition.
Sem LED: Suitable for cabinet interiors where visual coil status indication is not required. Choose RPF2BED if LED indicator is needed.
Montagem básica: RPZF2 base is mandatory; RXM small relay bases cannot be used. Plug-in design enables fast on-site replacement.

❌ Not Recommended Applications

Direct switching of main circuit for three-phase high-power motors (use contactors for motor main circuits; RPF only for auxiliary control)

Applications with extremely frequent switching cycles (limited contact life)

Loads exceeding 30A
