Product Overview
07KR51 1SBP260011R1001 is a member of ABB's 07KR series overcurrent protection relays, designed for electrical distribution systems and industrial equipment. It provides reliable overcurrent protection, ensuring the safe operation of electrical circuits by detecting abnormal current conditions and triggering protective actions (such as tripping circuit breakers) when thresholds are exceeded.
Technical Parameters
Protection Functions: Overcurrent protection (including instantaneous overcurrent, time-delayed overcurrent), short-circuit protection, and possibly earth fault protection (depending on specific configuration).
Current Setting Range: Typically supports adjustable current settings, e.g., 0.1A to 100A (specific ranges vary by model).
Time Delay Characteristics: Configurable time delays (inverse time, definite time) to coordinate with other protective devices in the system.
Input Voltage: Usually 24V DC or 110/220V AC (control power supply).
Output Contacts: Multiple relay output contacts (e.g., 1 normally open, 1 normally closed) for tripping or signaling.
Operating Temperature Range: -25°C to +70°C (operation); -40°C to +85°C (storage).
Protection Rating: IP20 (suitable for panel mounting in control cabinets).
Dimensions: Compact design, approximately 70mm × 120mm × 100mm (width × height × depth, subject to actual product).

Functional Features

Precise Protection: Uses high-precision current sensing components to accurately detect overcurrent and short-circuit faults.
Flexible Configuration: Allows users to set current thresholds, time delays, and protection logic via front-panel knobs or software (if supported), adapting to different system requirements.
Status Indication: Equipped with LED indicators to display operating status (e.g., power on, fault trip, normal operation) for quick fault diagnosis.
Reliability: Industrial-grade design ensures stable performance in harsh electrical environments, with resistance to electromagnetic interference (EMI) and voltage fluctuations.
Easy Integration: Compatible with standard electrical panels and can be connected to monitoring systems via auxiliary contacts for remote alarm and status feedback.

Application Fields

Low-voltage electrical distribution systems (e.g., distribution boards, switchgear).
Industrial machinery and equipment (motors, pumps, conveyors) to protect against overloads and short circuits.
Commercial buildings, power plants, and infrastructure projects requiring reliable electrical protection.
