Reliable, Compact Switching for Smart Building Performance
The DwyerOmega A/MSCS-A Current Switch delivers compact, adjustable sensing with a split core design, perfect for HVAC systems, pumps, and motorised assets in commercial or industrial buildings. It's stocked locally by Controls Traders, your trusted distributor in Australia offering local stock, expert guidance, and fast nationwide shipping.
What is the DwyerOmega A/MSCS-A Current Switch?
The Dwyer MSCS-A-Series is a miniature current switch featuring a split core and fixed set point, engineered for ease of use, precision, and durability. Designed to monitor medium current loads, it detects overcurrent, equipment failure, or motor belt loss in real time. With a self-powered, compact size build, it suits most applications (from new construction to retrofit jobs) without requiring wire disconnection.
This current switch features an adjustable set point range from 0.7A to 150A, N.O contact output, and installs quickly on the line side of motors, pumps, and compressors. It’s ideal for HVAC contractors and automation engineers needing a dependable status monitoring tool with consistent operating current visibility.
The split core design supports easy installation in tight or compact spaces, while plastic housing and non-condensing operation keep it running under various temperature limits. A solid choice for those who want reliable performance and agency approvals in place.
Key Benefits and Features
1. Adjustable Monitoring Range
Covers 0.7A to 150A, allowing precision across light to medium current loads in HVAC and electrical systems.
2. Split Core for Fast Retrofits
The split core design makes installation tool-free. Ideal for retrofits, upgrades, or servicing jobs where time matters.
3. Self-Powered Operation
No external power supply needed—cuts down on wiring and simplifies commissioning.
4. Prevent Equipment Downtime
Detects early signs of motor belt loss or mechanical failure, preventing costly equipment issues before they escalate.
5. Durable Plastic Housing
Engineered to withstand demanding environments with reliable isolation voltage and consistent operation under variable conditions.
6. BMS-Ready Integration
Perfect for logging contact closures and run-time tracking in building management systems or PLCs.
7. Compact, Service-Friendly Design
Fits into tight control panels and compact spaces with ease, speeding up deployment in the field.
Applications include:
- Smart building automation
- Commercial HVAC system monitoring
- Pump and motor runtime logging
- Industrial energy management
- Predictive maintenance scheduling
