Hydraulic-Magnetic and Magnetic Overcurrent Circuit Breakers 8350

Product catalog summary

Description: The document details the specifications and applications of the 8350 series magnetic and hydraulic-magnetic circuit breakers. These breakers are available in single to four-pole configurations with trip-free mechanisms and toggle or rocker actuation. They offer fast magnetic or hydraulically delayed switching characteristics, suitable for various applications such as communications systems, process control, and transportation. The breakers comply with the CBE standard EN 60934.

Technical Data: The circuit breakers have a voltage rating of 3 AC 415 V; AC 240 V 50/60 Hz, and DC 80 V. The current rating ranges from 0.1 to 70 A for multi-pole and up to 100 A for single and double pole configurations. They feature low temperature sensitivity, a typical life of 10,000 operations at rated current, and operate within an ambient temperature range of -40 to +85°C. The insulation coordination is rated at 2.5 kV with a degree of protection of IP40 for the operating area.

Ordering Information: The document provides detailed ordering information, including type number, mounting options, configuration, number of poles, color of the front face, terminal design, actuator configuration, characteristic curves, actuator color, and marking details. Various configurations are available to meet specific application needs.

Performance and Approvals: The circuit breakers are UL Recognized, CSA, and TÜV Certified, with various configurations offering different performance capabilities. They are suitable for use as component supplementary protectors, manual across-the-line starters, and molded case circuit breakers.

Characteristic Curves: The document includes typical time/current characteristic curves for different delay types (long, medium, short, and instantaneous) for both AC and DC applications. These curves are essential for understanding the trip time in relation to the current.

Accessories: Accessories such as toggle guards and splash covers (IP65) are available for additional protection and customization of the circuit breakers.
