Information About 3RV1021-1JA10
The 3RV1021-1JA10 is part of the Siemens SIRIUS 3RV10 family, engineered as a combined circuit breaker and motor protector for small to medium motor loads. It incorporates fixed magnetic trip elements for short-circuit response and adjustable thermal overload protection using built-in heater elements. Designed within the compact S0 frame size, it supports applications up to 690 V AC and delivers a 10 kA interrupt rating, making it suitable for industrial distribution systems. The unit accommodates screw-type terminals, IP20 front protection, and a snap-on mounting system for straightforward installation in motor starter assemblies or MCC panels. Compatible with 1-phase or 3-phase loads, it meets typical motor ratings across 115–575 V AC systems and tolerates a wide range of environmental conditions for dependable field use.
Key Features:
- Thermal-magnetic trip unit: Provides overload and short-circuit protection.
- Adjustable current range: 7–10 A setting for precise motor protection.
- 3-pole S0 frame: Supports single-phase or three-phase operation.
- 690 V AC voltage rating: Suitable for industrial power systems.
- Interrupt rating of 10 kA: Ensures reliable fault clearing.
- Compact dimensions: 45 × 96 × 97 mm for space-efficient installation.
- Screw terminal connections: Supports solid and stranded conductors.
- IP20 front protection: Shields terminal access from direct contact.
- Motor load capability: Up to 10 HP at 575 V AC, depending on phase.
- Snap-on mounting: Simplifies panel integration and replacement.
- Wide temperature tolerance: Operates from –20°C to +60°C.
The 3RV1021-1JA10 delivers the reliability and precision required for protecting motors in industrial control and automation systems.
