Cooling module Rittal SK 3307740, built-in display, input power 1125 W, 400/460 V, 50/60 Hz, stainless steel, grey

Rittal SK 3307740 is an industrial cooling module with a built-in display, intended for temperature control of electrical cabinets and enclosures. The unit is rated for an input power of 1125 W and is specified for operation on 400/460 V, 50/60 Hz three‑phase supply. Constructed from stainless steel with a grey finish, this cooling module provides a compact solution for consistent heat removal in control panels and other industrial housings. The Blue e series supports modular climate control and offers total cooling outputs in the 1.50–2.50 kW range for compatible models.

Advantages

The Rittal SK 3307740 integrates a built-in display for monitoring and basic control of enclosure temperature without additional external devices. Its stainless steel construction provides corrosion resistance and mechanical durability suitable for industrial environments. Designed for three‑phase supply at 400/460 V and 50/60 Hz, the unit fits installations where stable mains power is available and supports reliable heat removal up to the model’s rated capacity. The modular Blue e concept allows linking to IoT systems via a dedicated adaptor on compatible cooling units, enabling remote monitoring and integration when required.

Suitable for

• Temperature control of electrical cabinets and control panels in industrial environments
• Enclosures requiring a compact stainless steel cooling module with built‑in display
• Applications with three‑phase 400/460 V, 50/60 Hz supply
• Systems where modular integration with Blue e climate control components is needed

When it may not be suitable

This cooling module is intended for cabinets with compatible electrical connections and sufficient space for installation; it may not be suitable for small single‑phase installations or locations without three‑phase 400/460 V supply. If total cooling requirements exceed the rated cooling capacity of the chosen Blue e model, a higher‑capacity unit or multiple modules should be considered.

Key specifications

• Built‑in display for temperature monitoring and control
• Input power: 1125 W
• Cooling capacity: up to model range values within 1.50–2.50 kW for Blue e family (refer to exact model data)
• Supply voltage: 400/460 V, 50/60 Hz, three‑phase
• Housing material: stainless steel
• Finish: grey
• Designed for mounting on cabinet/climate control doors

How to use

Install the Rittal SK 3307740 into the designated opening of the cabinet or door according to the manufacturer’s mounting instructions and ensure proper electrical connection to a three‑phase 400/460 V, 50/60 Hz supply by a qualified electrician. Use the built‑in display to set and monitor desired enclosure temperature and to access basic operating parameters. Ensure adequate clearance around the module for airflow and service access. For networked monitoring or IoT integration, fit the Blue e IoT adaptor on compatible units and configure the connection following the Blue e system documentation.

What to consider before purchase

• Verify that your site has a compatible three‑phase 400/460 V, 50/60 Hz electrical supply
• Confirm the cabinet’s cooling requirement does not exceed the chosen model’s rated capacity
• Check mechanical fit and required cutout dimensions for door or panel mounting
• Decide if IoT/remote monitoring is needed and whether the Blue e IoT adaptor will be used

Usage recommendations

Operate and maintain the cooling module in line with Rittal's installation and service instructions: provide periodic cleaning of airways and heat exchanger surfaces, verify electrical connections and protective devices, and monitor performance via the built‑in display. For connected operation, use the Blue e IoT adaptor only on supported units and follow IoT adapter configuration guidelines.
