Onesto 50A 880V - 1000V 6kA DC 4 Pole Circuit Breaker

Product Overview

The Onesto KCD6 50A four-pole DC miniature circuit breaker provides overload and short-circuit protection for correctly specified direct-current circuits. Its 4-pole DIN-rail format suits compatible distribution boards and control panels, with a 6kA breaking capacity and a maximum operating voltage of 1000V DC when connected in the manufacturer's prescribed pole arrangement.

Key Features

• 50A rated current for circuits designed around this protection rating.
• 4-pole configuration for linked operation of the breaker poles.
• 6kA short-circuit breaking capacity for installations with a suitable prospective fault current.
• 1000V DC maximum operating voltage with the correct manufacturer-specified wiring.
• DIN-rail mounting for installation in compatible electrical enclosures.
• Designed to protect and control DC circuits against overloads and short circuits.

Applications

• DC distribution boards and control panels requiring 50A 4-pole circuit protection.
• Domestic and industrial DC electrical installations within the specified ratings.
• Solar-related DC circuits where the voltage, fault level, conductor size and pole arrangement meet the installation design.

Why Choose This Product?

This breaker offers a compact Onesto protection option for installers who require 50A DC circuit protection in a 4-pole format. It forms part of the KCD6 range, allowing the current rating to be selected to suit the circuit while retaining a consistent DIN-rail installation format.

Important Notes

• Installation and device selection must be completed by a qualified electrician in accordance with applicable South African wiring requirements and the manufacturer's instructions.
• The 1000V DC rating applies to the complete 4-pole assembly with the prescribed pole connections. Do not assume that each individual pole can interrupt 1000V DC.
• Observe the device's polarity, supply/load markings and wiring diagram, including any required series connections between poles. Do not infer the positive and negative conductor arrangement from the pole count alone.
• Select the current rating and trip characteristic to suit the load, conductor size and prospective fault current. Verify the trip characteristic against the supplied unit's marking before installation.
• This is a DC circuit breaker. Pole count does not indicate an AC phase rating, and an AC-only breaker must not be substituted.
• Product images illustrate the range; the current rating printed on the supplied unit will match the ordered version.
