The ZS10-BL (alternate code 1SNK508020R0000) is a 10mm² blue feedthrough terminal block manufactured by TE Connectivity (Entrelec), rated at 57A and designed for screw clamp DIN rail installation.
The Entrelec ZS10-BL is a screw clamp feedthrough terminal block offering a 1000V voltage rating and compact 8mm spacing, making it an efficient solution for high-density electrical panel wiring. Its blue colour coding and robust polyamide construction make it well suited to organised, professional control cabinet builds. With a short-time withstand current rating of 1200A at 1s, it delivers reliable performance in demanding installations.
Key Features
- Compact 8mm pitch: Accommodates conductors up to 10mm² in just 8mm spacing, saving valuable panel space without compromising capacity.
- 1000V voltage rating (IEC): Rated at 1000V AC/DC per IEC, making it suitable for solar applications and other high-voltage industrial circuits.
- 57A current rating: Supports demanding circuits with a short-time withstand current of 1200A at 1s for added safety margin.
- Flexible conductor acceptance: Accepts single flexible or rigid conductors from 0.5–10mm² and twin ferrule connections up to 2x 4mm², maximising wiring flexibility.
- Blue colour coding: Enables clear circuit identification within panels, reducing wiring errors during installation and maintenance.
- Polyamide insulation with UL 94V-0 rating: Self-extinguishing material provides strong fire resistance for safer panel assemblies.
- Dual DIN rail compatibility: Mounts on both TH35-7.5 and TH35-15 rails per IEC 60715, offering installation flexibility.
- IP20 protection: Protects against finger contact with live parts, meeting standard panel installation safety requirements.
Applications
The ZS10-BL feedthrough terminal block is widely used in industrial control panels, machine building, power distribution boards, and solar energy installations where its 1000V DC/AC IEC rating is particularly valuable. Its blue colouring makes it a popular choice for neutral conductor identification in panel wiring. It is also suited to marine, railway trackside equipment, and hazardous location installations where robust, certified components are required.
Standards and Approvals
The ZS10-BL holds CB, cUL, CSA, ATEX, DNV, BV, RINA, RMRS, and EAC certifications, complies with IEC 60947-7-1 and UL 1059, carries CE Declaration of Conformity, and is RoHS compliant per EU Directive 2002/95/EC.
Manufactured by TE Connectivity (Entrelec) in Poland. Order code: ZS10-BL / 1SNK508020R0000.
Frequently Asked Questions
What cable sizes can be connected to the ZS10-BL?
The ZS10-BL accepts single flexible or rigid conductors from 0.5–10mm², and two conductors per clamp up to 2x 4mm². It also supports insulated ferrules up to 6mm² and twin ferrules up to 2x 4mm².
What DIN rails is the ZS10-BL compatible with?
It mounts on both TH35-7.5 and TH35-15 DIN rails in accordance with IEC 60715.
Is the ZS10-BL suitable for solar applications?
Yes — the ZS10-BL is rated at 1000V AC/DC per IEC, making it well suited for solar panel wiring and photovoltaic installations.
How does the blue ZS10-BL differ from the standard grey version?
The ZS10-BL is identical in electrical and mechanical performance to the standard grey version — the blue colour is used for circuit identification, typically to denote neutral conductors within a panel.
