Description

SACE15RE13: Product Overview
This device is a molded case circuit breaker (MCCB) within ABB’s SACE RE Series, designed for low-voltage power distribution systems requiring reliable circuit protection. In an electrical architecture, it functions as a protective switchgear component, positioned in distribution boards, motor control centers (MCCs), or panelboards to safeguard downstream equipment (e.g., motors, transformers, lighting circuits) from abnormal currents. Its role is to monitor current flow, detect overloads (prolonged excess current) or short circuits (sudden high-magnitude current), and interrupt the circuit within milliseconds to prevent thermal damage or fire hazards.
The core functionality involves a dual-protection mechanism: a thermal element (bimetallic strip) for overload protection (adjustable trip threshold) and an electromagnetic element (solenoid) for short-circuit protection (fixed instantaneous trip). It supports 3-pole configuration for three-phase circuits, with a 25kA ultimate breaking capacity (Icu) to handle severe fault currents. The breaker also includes a visible trip indicator and auxiliary contacts for remote status signaling.
It belongs to the SACE RE Series, a product family optimized for industrial and commercial power distribution. The platform’s benefits include compliance with IEC 60947-2 (MCCB standards), modular design for easy integration with ABB’s System Pro M compact panels, and global certification (UL, CE, CCC) for cross-regional deployment. This ensures interoperability with existing ABB components and third-party systems.

Core Features & Customer Value​
The breaker’s design prioritizes protection reliability, operational flexibility, and ease of maintenance. The 25kA breaking capacity ensures safe interruption of high-fault currents in industrial settings (e.g., short circuits in motor circuits), protecting transformers and switchgear from catastrophic failure. For engineers, this eliminates the need for oversized upstream breakers, reducing system costs.
Thermal-magnetic trip characteristics balance sensitivity and selectivity: the adjustable thermal element (0.8–1.0x In) accommodates load variations (e.g., motor starting currents), while the magnetic element trips instantaneously at 10–14x In for short circuits. This prevents nuisance tripping during normal operation yet responds rapidly to faults—critical for maintaining production uptime in manufacturing lines.
The 3-pole configuration supports balanced three-phase loads, with phase-barriers to prevent arc propagation between poles. For facility managers, this reduces installation complexity compared to single-pole breakers. The visible trip indicator (red flag) and auxiliary contacts (NO/NC) enable quick visual diagnosis and integration with SCADA systems for remote monitoring.
Compliance with IEC 60947-2 ensures global acceptance, while ABB’s System Pro M panel compatibility simplifies cabinet integration. Modular construction allows front-panel replacement of internal components (e.g., trip units) without removing the breaker from the panel, minimizing downtime during repairs.

Typical Applications​
In an automotive assembly plant, the breaker protects a 15A motor circuit powering a conveyor belt. Its thermal element accommodates the motor’s 6x In starting current without tripping, while the 25kA breaking capacity interrupts a short circuit caused by a damaged cable, preventing damage to the motor and drive.
At a commercial office building, it safeguards a 3-phase lighting circuit (15A total load) in the main distribution board. The IP40 rating resists dust in the panel, and the adjustable thermal trip aligns with seasonal lighting load changes (e.g., reduced winter hours).
In a wastewater treatment plant, the breaker is installed in an MCC to protect a 15A pump circuit. Auxiliary contacts signal a trip to the SCADA system, enabling remote reset after clearing a clogged impeller (overload cause). The -25°C rating withstands unheated panel temperatures near outdoor pumps.
