Product catalog summary

Overview: The document provides technical specifications and guidelines for single pole distribution blocks, which are used for electrical connections. These blocks are designed for both copper and aluminum conductors and can be used in various applications, including solar power systems.

Specifications:

Material: Tinned copper or aluminum with thermoplastic.
Design: Hinged and removable screw retaining cover for easy inspection and connection confirmation.
Modularity: Snap-together blocks for creating multi-pole power blocks.
Mounting: Can be clipped onto DIN rail or mounted to a panel with screws.
Compliance: RoHS compliant and conforms to EN 45545 with HL3 classification for chapter R23 and HL2 for chapter R22.
Halogen-free.

Performance Parameters:

Fill Ratio: 95%.
Max Working Voltage: 1,000 VAC/DC (IEC), 600 V (UL).
Current Ratings: Vary by model, ranging from 80 A to 1,250 A (IEC) and 85 A to 950 A (UL/CSA).

Product Variants: The document lists various models with different current ratings, conductor sizes, and materials. Each model is specified with its part number, article number, and certifications such as CE, ERIFLEX UD, CSA, cURus, EAC, EN 45545, and RoHS.

Design Guidelines:

Derating Coefficient: Provided for ambient temperatures ranging from 30°C to 75°C to maintain a working temperature of 85°C.
Jumper Usage: Increase outputs with one input using a jumper for blocks with a max current rating up to 160 A.
Application: Suitable for solar applications due to high max working voltage.

Warnings: nVent products must be installed and used according to the provided instruction sheets and training materials to avoid malfunction, property damage, or injury.

Legal and Trademark Information: The document includes legal disclaimers and trademark information related to nVent and other entities.
