Product Information
Full details
The ABB E 91/32 is a single-pole fuse switch disconnector designed for robust overcurrent and short-circuit protection in electrical systems. It is ideal for electricians and system integrators who need reliable protection for circuits handling 10x38 mm fuses, offering the critical ability to switch under load. A key limitation is its lack of a blown fuse indicator, requiring a separate method to check fuse status.

FAQs
Does the E 91/32 have a blown fuse indicator?
No, the ABB E 91/32 does not feature a blown fuse indicator. Fuse status must be checked manually.
What size fuses does this disconnector accept?
The E 91/32 is designed to accept 10x38 mm fuses.
Can I switch this disconnector while the circuit is live?
Yes, the E 91/32 is designed for switching under load.
How is the E 91/32 mounted?
It is designed for mounting on a standard 35 mm DIN rail.
What is the degree of protection (IP rating) of this device?
The device has an IP20 rating, offering protection against solid objects larger than 12.5mm.
Can this disconnector be secured against tampering?
Yes, it can be lead-sealed in the closed position or locked with a padlock in the open position.
What is the width of the E 91/32?
The width is 18 mm, which corresponds to 1 modular spacing.
Troubleshooting
Device will not close or open
Ensure the fuse is correctly inserted and that the disconnector is not locked or sealed. Check for any physical obstructions.
Overheating at terminals
Verify that the connected conductors are properly sized and securely tightened. Check the fuse for correct rating.
Fuse blows repeatedly
Investigate the circuit for the cause of the overload or short circuit. The disconnector is functioning correctly by interrupting the fault.
Pros and Cons
Pros
- Provides essential overcurrent and short-circuit protection.
- Enables safe switching under load conditions.
- Durable construction with high-temperature resistant, self-extinguishing thermoplastic.
- Secure installation via standard DIN rail mounting.
- Lockable feature enhances safety and prevents unauthorized operation.
Cons
- Does not include a blown fuse indicator, necessitating manual checks.
- Single-pole design limits application to single-phase circuits or specific protective functions.
- Requires separate fuse elements for operation.
Setup, Compatibility & Care
Setup:
- Ensure the power to the circuit is completely disconnected before installation.
- Mount the E 91/32 fuse disconnector onto a standard 35 mm DIN rail.
- Insert the appropriate 10x38 mm fuse into the fuse holder.
- Connect the incoming and outgoing electrical conductors to the designated terminals.
- The device can be lead-sealed in the closed position or padlocked in the open position for security.
Compatibility:
- Compatible with 10x38 mm fuses.
- Designed for use with S 200 series busbars.
- Suitable for use in electrical enclosures and control panels.
Care:
- The E 91/32 is a maintenance-free device under normal operating conditions.
- Keep the exterior clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning if necessary.
- Periodically inspect electrical connections for tightness.
- Due to the absence of a blown fuse indicator, fuses should be checked for continuity as part of routine electrical maintenance.
