Fuses & Fuse Holders
Shop genuine ABB pluggable interface relays and bases at Hagar, your trusted industrial automation stockist holding physical stock in South Africa.
Engineered for safe galvanic isolation, clean signal conditioning, and reliable power amplification, our CR-P, CR-M, and CR-U ranges act as a vital buffer between sensitive controllers (like PLCs) and higher-power panel equipment.
This includes industrial contactors and motorised change-over switches for complete system integration.
ABB fuse technology offers high breaking capacities (>50kA) ideal for solar inverters, variable speed drives, and transformer protection.
ABB E 90 Series Fuse Holders: IP20 fingerprint-safe DIN-rail holders with isolated extraction drawers for safe, toolless fuse replacements.
Optical Blown-Fuse Indicators: Specialized E 90 models with built-in LEDs that illuminate instantly when a fuse blows, streamlining panel diagnostics.
Industrial Cylindrical Fuses: Stocked in standard 10.3 x 38 mm, 14 x 51 mm, and 22 x 58 mm industrial dimensions across multiple current ratings.

Frequently Asked Questions
What are the primary advantages of the ABB E 90 series fuse holders?
The ABB Formula series is designed for standard, fixed application parameters up to 630A with pre-set trip units, making it a highly cost-effective choice for basic distribution panels. The Tmax XT series offers advanced, interchangeable electronic trip units, higher breaking capacities, and integrated connectivity options for complex industrial power management up to 1600A.
Do ABB fuse holders feature visual indicators to identify a blown fuse?
Yes, the Tmax XT range is highly modular. Accessories such as shunt trips, undervoltage releases, auxiliary contacts, and motorized operators can be installed quickly and safely directly in the field without requiring specialized tools or complex modifications to the breaker core.
When should I choose an ABB fuse switch disconnector over a standard miniature circuit breaker (MCB)?
Fuse switch disconnectors are preferred in applications with exceptionally high prospective short-circuit fault currents (often exceeding 50kA or 100kA), such as primary incoming lines or near large transformers. Fuses react faster to extreme short circuits than mechanical breakers and provide highly cost-effective, specialized protection for sensitive electronics or power semiconductors.
What sizes of cylindrical fuses do your ABB fuse holders accommodate?
Our range covers the standard industrial cylindrical fuse sizes, most commonly the 10.3 x 38 mm profile for control circuits and auxiliary protection. For higher-power distribution parameters, we supply larger industrial profiles including 14 x 51 mm and 22 x 58 mm configurations, supporting a wide range of current ratings.
