Overview
The IDEC NRAS1100 circuit protector is a compact, single-pole thermal-magnetic circuit breaker designed for reliable overcurrent protection in industrial electrical systems. With a 2A rated current, 250VAC/65VDC voltage rating, and standard panel-mount form factor, this breaker delivers dependable protection for control circuits, motor starters, and instrumentation in manufacturing and automation environments.
Key Features
- Thermal-magnetic trip mechanism — rapid response to short circuits and sustained overload conditions
- 1-pole design — suitable for single-phase protection circuits
- Round lever operating handle — ergonomic, field-replaceable design for manual reset capability
- 250VAC / 65VDC dual-voltage rating — supports both AC and DC control circuits
- Panel-mount configuration — standard DIN-rail compatible installation
- UL, cUL, VDE, and CE certifications — meets major international safety standards
Technical Specifications
The NRAS1100 series uses a current-trip internal circuit with no inertia delay. Amperage options range across the NRA series (0.75A to 15A+), making the 2A variant suitable for low-current control applications. All units feature identical voltage and mounting characteristics across the series.
Typical Applications
- PLC input/output module protection
- Sensor and instrumentation circuit protection
- Control relay circuits in automation panels
- Low-current DC supply protection (65VDC rated)
- Field-installed overcurrent backup in industrial controls
Compatibility & Replacements
Compatible With
- Standard industrial control panels and enclosures
- DIN-rail mounted systems
- 250VAC / 65VDC DC power supplies
- Allen-Bradley, Siemens, and general PLC I/O circuits
- Manufacturing and machinery automation systems
Replaces / Drop-In Replacement For
The NRAS1100 series provides direct replacement capability within IDEC’s NRA circuit protector line. Other NRAS1100 variants at different amperage ratings use identical mounting and electrical characteristics. Verify your specific amperage requirement (0.75A, 2A, 5A, 10A, 15A, etc.) before ordering to ensure proper circuit protection.
Works With
- IDEC pushbutton and indicator light enclosures
- Standard 35mm DIN-rail mounting systems
- Industrial control software and HMI platforms (protection device itself is hardware-based)
- Both AC and DC control architectures
