Contactors & Relays
Reliable switching and protection components for industrial control systems.
Overview
Basiia supplies contactors, protection relays, auxiliary relays, and associated control components for industrial motor control, power switching, and protection applications. We source from leading manufacturers including Siemens, Schneider Electric, ABB, Eaton, and Omron — providing the right component for each application based on current rating, duty cycle, environmental conditions, and communication requirements. Our supply includes full documentation, traceability, and manufacturer certificates.
Typical Applications
- Motor starting and reversing contactors
- Power switching for heating and lighting loads
- Motor overload and protection relays
- Numerical protection relays for feeders and transformers
- Auxiliary and interposing relays for control circuits
- Solid-state relays for high-cycle switching
- Safety relays for machine guarding and E-stop circuits
- Time delay and monitoring relays
Key Features
Engineered for Performance
AC & DC Contactors
IEC and NEMA rated AC contactors from 9 A to 2000 A for motor starting, capacitor switching, and power distribution — with AC and DC coil options, auxiliary contact blocks, and surge suppression.
Thermal & Electronic Overload Relays
Bimetallic thermal overload relays for standard motor protection; electronic overload relays with phase loss, thermistor, and ground fault detection — adjustable trip class and manual/auto reset.
Numerical Protection Relays
Microprocessor-based protection relays for overcurrent, earth fault, differential, motor, and feeder protection — with SCADA communication (Modbus, IEC 61850), event logging, and fault recording.
Safety Relays
Safety relays and safety controllers to IEC 62061 / ISO 13849 for emergency stop, light curtain, door interlock, and two-hand control circuits — achieving SIL 2/3 and PLd/PLe safety integrity.
Auxiliary & Interposing Relays
DIN-rail mounted auxiliary relays for signal isolation, voltage conversion, and contact multiplication in PLC and control panel applications — with LED indication and plug-in socket bases.
Manufacturer Traceability
All components supplied with manufacturer test certificates, material traceability, and country of origin documentation — supporting project quality plans and third-party inspection requirements.
